Lucius Mussius Aemilianus (d. 261 or 262) was a Roman usurper.Mussius Aemilianus probably was of Italian stock. He was an officer in the Roman army under Philip the Arab and Valerian. Under the latter he became Praefectus augustalis of Egypt. He supported the rebellion of the Macriani against Gallienus (260-261). When the Macriani were defeated he probably proclaimed himself emperor.Gallienus sent his general Aurelius Theodotus to Egypt to deal with Aemilianus.
